Outch! Your disk is badly corrupted!

It means that two or more files are sharing at least on data block (cluster).

An ANALYZE/DISK_STRUCTURE should report this, but of course it does not know to which file the data belongs.

You can try to disable the automatic system disk rebuild like I have writen in your other thread (ACP_REBUILDSYSD=0). But, honestly, it looks like you disk's structure is really, really badly corrupted and I would not try to recover from it. In my opinion it's a waste of time. Some other data blocks might have been overwritten and you might not find out of they are not doubly mapped.

Sorry, but you need to do a conversational boot first. It sounds like you are on a VAX system. Assuming that you boot from root [SYS0] (you can check that with:

>>> SHOW BFLG
or
>>> SHOW BFLAG

depending on model) I would do this first:

>>> BOOT/R5:1

The system should then respond with:
SYSBOOT>

where you enter:
SYSBOOT> SET ACP_REBLDSYSD 0
SYSBOOT> EXIT

Hello,
What a bad day, I don't know who setup this system. The boot was default to dua0: which is not excess. I try to set boot to dub0: which the disk have error on it and no go.
I try boot/r5:1 the system trying point at dua0: it will not work since there is no drive under this name. I have a complete images backup how can i install it, since I can't get to the $ sign.

type show boot error ?18 inv dgt, try all method you recommand just can't get to the sys$boot >

I'm truly sorry for all the mess you are going through, but treat it as a great learning experience and I'm sure you feel a bit better.

You can usually override the boot device with:
>>> boot/R5:1 DUB0

I wonder, what system are you working with? Model number? The error message looks like from a MicroVAX II. If I recall correctly, this is a system with a so-called 'sniffer boot' which tries a fixed set of devices in a fixed order and you cannot set a default boot device.

It might be possible to set the system not to automatically boot after power on so that you can choose the boot devicve.

finally using the boot/r5:1 dub0 I can get to the sysboot> and i follow the bypass startup and login procedures
sysboot> set/startup opa0:
continue
it show vax/vms v5.2....
it try to access my bad disk again
my lord... what else can I try

Re: what is this means ?

SCC_2 — Mon, 30 May 2005 14:57:04 GMT

yes, you are right the system is a micro vax II and they updated it call micro vax 3900 with a micro vax II case (box).

The file must be bad within the bootup version 5.2, the system can't boot up after I get the sys$boot show up

>>> b/r5:1 dub0
sysboot> set acp_rebldsysd 0
sysboot > exit
vax/vms version v5.2 major versio id = 1 minor version id = 0
and it sit there hrs, no respone.
I need to get back to the $ sign somehow to run the backup/restore the file.
Any idea how to do that ?

You need to boot from standalone backup - probably from another disk, tape or CD.

from a disk or CD
BOOT/R5:E0000000 DUxx

from tape (if you have standalone backup kit on tape)
BOOT MUxx

you will be prompted to enter the date and time then get a $ prompt at which you can only perform BACKUP commands.

Ideally restore the whole disk as it looks like the file structure is corrupt.

If you have a later VMS CD then parhaps an attempt to repair could be tried.

Don't know is the tape (td50) is too old or what. boot/r5:e0000000 mua0 (I heard the tape drive spinning back and forward)then
error come back sayinng ?4d devoffline, mua0
? o6 hlt inst
pc = 00800e0a failure.

I have another mirovax 3100 model 80 running, using v5.5 instead of V5.2, I guest I can build another standalone tape on that VAx and use it over here, Can I ?, even the Vms version are not the same.
Thanks !

Ian Miller. — Tue, 31 May 2005 09:46:10 GMT

to build a tape on your V5.5 system do
@SYS$UPDATE:STABACKIT MUA0:

Re: what is this means ?

Volker Halle — Tue, 31 May 2005 09:49:07 GMT

SCC,

you shouldn't specify the system root when booting from tape, just:

>>> B MUA0

should be sufficient.

And yes, you can built a standalone backup tape on another node (and VMS version) to be booted on your system:

$ @SYS$UPDATE:STABACKIT MUAn:

Thanks, I will try that. But I am very sure that tape must be old.
SCC

Re: what is this means ?

SCC_2 — Tue, 31 May 2005 14:25:26 GMT

My system was running under vms v5.2 and the standalone tape doesn't work maybe is too old. I create another standalone tape on another Vax it run under vms V5.5. I insert the standalone on v5.5 hope it will boot up my system( the dead one) but there is an error message % sysboot-f-unexpected machine check and bring me back to >>>.
Is there anyway I can by pass this.
Thanks !

at per perv. at the end of the error line
it say
?05 dbl err.

Re: what is this means ?

Volker Halle — Wed, 01 Jun 2005 00:43:26 GMT

SCC,

too bad, this looks like a CPU/memory error on your V5.2 system. DBL ERR is a double error, i.e. another HW error occured while handling a hardware error. The CPU then just halts.

To really make sure, that your SA-backup tape is o.k., try to boot it on your V5.5 system.

Volker.

Re: what is this means ?

SCC_2 — Wed, 01 Jun 2005 09:36:17 GMT

I can't shutdown the other Vax at this point, Since other users is using it at business hour, I am going to make another standalone tape see it will work or not.

Is there another other option I can get try.

Thanks !
